1、高倍率鋰電池使(shi)用(yong)薄正(zheng)極(ji)(ji)比厚正(zheng)極(ji)(ji)的(de)容量(liang)要低，在相(xiang)同(tong)倍(bei)率(lv)下放(fang)電時.流(liu)過正(zheng)極(ji)(ji)的(de)電流(liu)密度不一(yi)樣，在相(xiang)同(tong)倍(bei)率(lv)下，流(liu)過薄正(zheng)極(ji)(ji)電池(chi)的(de)電流(liu)密度更小，電化(hua)學反應的(de)極(ji)(ji)化(hua)相(xiang)對較(jiao)小，故放(fang)電效果比厚正(zheng)極(ji)(ji)電池(chi)好，降低正(zheng)極(ji)(ji)的(de)厚度，可有效地(di)提高電池(chi)的(de)放(fang)電倍(bei)率(lv)。

在(zai)大致相同的(de)(de)放(fang)電電流密度下(xia)，薄正極電池的(de)(de)放(fang)電利(li)用率(lv)更高。這是因為(wei)電池在(zai)高倍率(lv)放(fang)電時，活性物質的(de)(de)反應速度很快，要求離子能從材料中(zhong)迅速地(di)嵌(qian)脫。極片若較厚(hou)，加長了離子運(yun)動(dong)的(de)(de)路徑，增加了離子運(yun)動(dong)的(de)(de)阻力，最終影響到電池容量的(de)(de)發揮揮。

2、導(dao)電(dian)劑含量對高倍(bei)率鋰(li)電(dian)池的影(ying)響

正(zheng)(zheng)極(ji)中的(de)(de)(de)導電(dian)(dian)(dian)(dian)(dian)劑含量(liang)(liang)對電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)高倍(bei)率(lv)放(fang)電(dian)(dian)(dian)(dian)(dian)性能(neng)有明(ming)顯的(de)(de)(de)影響。正(zheng)(zheng)極(ji)導電(dian)(dian)(dian)(dian)(dian)劑的(de)(de)(de)含量(liang)(liang)是影響lQ0C高倍(bei)率(lv)放(fang)電(dian)(dian)(dian)(dian)(dian)性能(neng)的(de)(de)(de)關鍵因素。正(zheng)(zheng)常電(dian)(dian)(dian)(dian)(dian)池(chi)不(bu)能(neng)進行1Q0C倍(bei)率(lv)放(fang)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)主要原(yuan)因是正(zheng)(zheng)常正(zheng)(zheng)極(ji)配方中的(de)(de)(de)導電(dian)(dian)(dian)(dian)(dian)劑含量(liang)(liang)不(bu)足。大電(dian)(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)(dian)時電(dian)(dian)(dian)(dian)(dian)子不(bu)能(neng)及時地轉移，極(ji)化內阻迅速增大，使電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓很快降(jiang)低到(dao)放(fang)電(dian)(dian)(dian)(dian)(dian)終止電(dian)(dian)(dian)(dian)(dian)壓。

3、負極材(cai)料(liao)對高倍率鋰電池(chi)的影(ying)響

人(ren)(ren)工(gong)石墨和(he)MCMB，不(bu)同(tong)類型的負極材料對高倍(bei)率放電(dian)性能有(you)較大的影響，人(ren)(ren)工(gong)石墨的比表面積比MCMB要大很(hen)多，但(dan)高倍(bei)率放電(dian)性能遠(yuan)不(bu)如(ru)MCMB.

MCMB的(de)(de)表(biao)面(mian)形貌類似球形，有(you)利(li)于顆(ke)粒(li)的(de)(de)最(zui)大堆積(ji)和極(ji)片壓實，使活性材料顆(ke)粒(li)之間(jian)的(de)(de)接觸更好(hao)。電子導電性也更好(hao)；人工石墨的(de)(de)表(biao)面(mian)形貌類似條棒狀，活性材料顆(ke)粒(li)的(de)(de)接觸會較少.或出現空隙，導致(zhi)電極(ji)的(de)(de)導電性下降，因此大電流放電性能不如MCMB。

4、尺寸大小(xiao)對高倍率鋰電池的影響

不(bu)(bu)用型號的(de)(de)電(dian)(dian)池放(fang)電(dian)(dian)性能，相(xiang)同配方、不(bu)(bu)同型號電(dian)(dian)池的(de)(de)高倍率(lv)(lv)放(fang)電(dian)(dian)性能也(ye)不(bu)(bu)一(yi)樣(yang)，表(biao)現為電(dian)(dian)池面積大，高倍率(lv)(lv)放(fang)電(dian)(dian)性能較好，因此相(xiang)同倍率(lv)(lv)下的(de)(de)放(fang)電(dian)(dian)容量明顯大。

5、電(dian)解液(ye)對高倍率(lv)鋰電(dian)池的影響

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)基準(zhun)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)和功(gong)能(neng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)的(de)高(gao)倍(bei)(bei)率(lv)(lv)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)曲(qu)線可以(yi)看出：l00C倍(bei)(bei)率(lv)(lv)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)，不(bu)同電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)首(shou)次放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容量差別(bie)很小；20.0C倍(bei)(bei)率(lv)(lv)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)，基準(zhun)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)首(shou)次放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容量明(ming)顯不(bu)如功(gong)能(neng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，甚(shen)至不(bu)可以(yi)正常放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。對于聚合物鋰(li)離(li)子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)來(lai)說，要(yao)實現l00C高(gao)倍(bei)(bei)率(lv)(lv)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)普通三元電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)可以(yi)滿(man)足要(yao)求(qiu)(qiu).若要(yao)求(qiu)(qiu)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)倍(bei)(bei)率(lv)(lv)更高(gao)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)要(yao)進行優化(hua)。功(gong)能(neng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)對高(gao)倍(bei)(bei)率(lv)(lv)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)常見的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓先(xian)降后升的(de)問題.有明(ming)顯的(de)改善(shan)作(zuo)用，說明(ming)在更高(gao)倍(bei)(bei)率(lv)(lv)下放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)，應(ying)加強(qiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)功(gong)能(neng)化(hua)作(zuo)用的(de)優化(hua)。
